Pros: Great resolution, highs are incredible, possibly the best value in IEM's

Cons: Microphonic cable, needs a bit of power to sound its best

In short: I love these headphones; they are an incredible value and all head-fiers should pick a pair up. While they are not as "fun" as my Grado cans or Fischer Audio IEM's, the RE0 has a neutral sound and can easily distinguish between instruments. Cymbals and acoustic guitar sound lifelike and while the bass impact may be below average, the accuracy of the lows on the RE0 have me preferring them to the lows on my bass-centric Fischer Audio Eterna.

These are an incredible value at 79.99 and everyone should at least consider them for their next IEM purchase.
